Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an earthquake-resistant pipe pile structure. Background Technology

[0002] In the field of construction engineering, especially in infrastructure construction in earthquake-prone areas, pile foundations serve as a crucial support system for buildings, and their seismic performance directly affects the safety and stability of the entire structure. When geological conditions are poor and the bearing capacity of the foundation is low, pile foundations must be used. Concrete pipe piles are driven into the ground one by one, transferring the weight of the building above to the lower soil layer with higher bearing capacity. If the lower soil layer with high bearing capacity is very deep, the friction between the pile foundation and the surrounding soil can also be used to support the weight of the building above.

[0003] In the existing technology, most pipe piles are narrower at the bottom than at the top, and the outer surface of the pipe piles is relatively flat and smooth. Although this can speed up the piling efficiency to a certain extent, it will reduce the seismic performance of the pipe piles to a certain extent. Therefore, a seismic-resistant pipe pile structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an earthquake-resistant pipe pile structure that solves the problems mentioned above.

[0005] To achieve the above objectives, a seismic-resistant pipe pile structure is provided, comprising an outer pipe, a cone head fixedly connected to the lower end of the outer pipe, and a through hole on the outer side; a reinforcing core is provided inside the outer pipe, and a stabilizing mechanism is provided on the reinforcing core; the stabilizing mechanism includes a fixed disk, a turntable rotatably connected inside the fixed disk, a guide groove on the turntable, a reinforcing rod slidably connected to the fixed disk located outside the turntable, a roller fixedly connected to the inner end of the reinforcing rod, the roller being located in the guide groove and slidably connected to the roller, the reinforcing rod slidably connected to the through hole, the reinforcing core being fixedly connected to the turntable, a cover plate being fixedly connected to the upper side of the fixed disk, and the reinforcing core being rotatably connected to the cover plate.

[0006] According to the earthquake-resistant pipe pile structure, there are several through holes, which are evenly distributed. Four through holes form a group and correspond one-to-one with the stabilizing mechanism.

[0007] According to the earthquake-resistant pipe pile structure, the guide groove is arc-shaped, and there are four guide grooves that are evenly distributed.

[0008] According to the aforementioned seismic-resistant pipe pile structure, a gap is provided between the outer pipe and the reinforcing core.

[0009] According to the earthquake-resistant pipe pile structure, the outer side of the fixing plate is fixedly connected to the inner wall of the outer pipe.

[0010] According to the earthquake-resistant pipe pile structure described above, the reinforcing support rods correspond one-to-one with the through holes.

[0011] According to the earthquake-resistant pipe pile structure, the reinforcing core penetrates the turntable located in the middle position.

[0012] According to the aforementioned seismic-resistant pipe pile structure, the voids are filled with concrete.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with the existing technology, by setting a stabilizing mechanism inside the outer tube, after the outer tube is installed, the rotating reinforcing core drives the turntable to rotate. At the same time, under the action of the turntable and the guide groove, the reinforcing support rod extends outward and passes through the through hole to be fixed in the ground, which makes the outer tube more stable and thus improves the seismic performance of the concrete pipe pile.

[0015] 2. Compared with existing technologies, the seismic performance of the outer tube can be further enhanced by injecting special concrete into the gap between the reinforcing core and the outer tube. Attached Figure Description

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides an earthquake-resistant pipe pile structure, which includes an outer pipe 1 made of metal. The lower end of the outer pipe 1 is fixedly connected to a cone head 11, and a through hole 12 is provided on the outer side. The cone head 11 adopts a variable cross-section design, and the included angle of the tip is determined by fluid dynamics simulation to be the optimal soil entry angle (usually controlled between 8° and 12°). This can reduce the disturbance to the surrounding soil and effectively guide the displaced soil to climb upward along the predetermined slip surface.

[0025] There are several through holes 12, which are evenly distributed. Four through holes 12 form a group and correspond one-to-one with the stabilizing mechanism 3. The through holes 12 are arranged in a diamond shape to form an independent working unit, which not only ensures that the overall rigidity of the pile body is not weakened, but also provides a channel for the subsequent intervention of the stabilizing mechanism. The outer tube 1 is equipped with a reinforcing core 2, and there is a gap 4 between the outer tube 1 and the reinforcing core 2. The reinforcing core 2 is made of high-strength alloy steel, and the gap 4 is filled with concrete. The concrete is a special concrete with fiber-reinforced material, which has excellent shear strength and toughness recovery ability and can generate controllable cracks to consume energy under the action of seismic waves. The stabilizing mechanism 3 is installed on the reinforcing core 2, and the reinforcing core 2 passes through the turntable 33 located in the middle position.

[0026] The stabilizing mechanism 3 includes a fixed disk 31, and a turntable 33 is rotatably connected inside the fixed disk 31. The turntable 33 is connected to the fixed disk 31 through a bearing. The bearing assembly adopts a combination of double-row angular contact ball bearings and crossed roller bearings to ensure sufficient axial positioning accuracy while bearing radial loads. The turntable 33 is provided with guide grooves 34. The guide grooves 34 are arc-shaped and there are four guide grooves 34, which are evenly distributed. The guide grooves 34 are hardened by a special heat treatment process, and their radius of curvature precisely matches the movement trajectory of the reinforcing support rod. When the reinforcing core 2 is manually rotated, the power is transmitted to the turntable 33 through the keyway coupling, causing the rollers 36 installed in the guide grooves 34 to slide along a predetermined path.

[0027] A reinforcing rod 35 is slidably connected to a fixed plate 31 located outside the turntable 33. The reinforcing rod 35 corresponds one-to-one with the through hole 12. A roller 36 is fixedly connected to the inner end of the reinforcing rod 35. The roller 36 is connected through a rotating shaft. The roller 36 is located in the guide groove 34 and is slidably connected. The reinforcing rod 35 is slidably connected to the through hole 12. The reinforcing core 2 is fixedly connected to the turntable 33. A cover plate 32 is fixedly connected to the upper side of the fixed plate 31. The reinforcing core 2 is rotatably connected to the cover plate 32.

[0028] Working principle: In use, the outer tube 1 is first fixed in the ground by the cone head 11. At this time, the surface of the outer tube 1 is smooth, which can speed up the efficiency of pile driving. Then, the reinforcing core 2 is rotated, which drives the turntable 33 to rotate. At the same time, under the action of the turntable 33 and the guide groove 34, the reinforcing support rod 35 is driven to extend outward and pass through the through hole 12 and be fixed in the ground, so that the stability of the outer tube 1 is better, thereby improving the seismic performance of the concrete pipe pile. After the fixing is completed, concrete is injected into the gap 4 to further enhance the seismic performance of the outer tube 1.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
